Wuxue is a large planting and breeding city in Hubei province.For fulfilling the green development of agriculture in Wuxue city，it is of great significance to estimate the crop straw and livestock manure resources，evaluate the land carrying capacity and discuss the potential of saving fertilizer by green planting and breeding.Based on the statistical data，this paper estimated the nutrient resources of crop straw and livestock manure，and its potential of fertilizer replacement in Wuxue city.Current land carrying capacity and land carrying capacity index were also evaluated.The results showed that the straw yield of main crops in Wuxue city was 531900 tons in 2020，and the livestock and poultry breeding were 953300 pig equivalents.Theoretical recoverable amount of straw and livestock manure nutrient resources were 11900 and 8200 t in Wuxue city，respectively，which could reduce 27.4% and 18.9% of chemical fertilizer consumption，respectively.The theoretical cost savings of chemical fertilizer were 61.93 million yuan and 40.77 million yuan，with a total of 102.70 million yuan.In 2020，the soil carrying capacity indexes of nitrogen and phosphorus from livestock manure in Wuxue were 0.80 and 0.48，respectively.At present，the livestock and poultry production have not exceeded the land carrying capacity of Wuxue.However，the livestock and poultry production were close to the upper limit of nitrogen carrying capacity.
